OPPO Find 5 Smartphone Announced With Dirac HD Sound

December 13, 2012

UPPSALA, Sweden, December 13, 2012 /PRNewswire/ –

Dirac Research announces the introduction of a new smartphone with Dirac HD Sound
optimization built in. At the OPPO Find 5 launch event held in Beijing’s 798 Art District
on Wednesday, in front of over 500 members of the international press, Dirac’s CEO spoke
of the high-class sound quality obtained through the use of innovative sound processing.

OPPO yesterday announced the launch of their flagship smartphone Find 5. Dirac’s CEO
Dr. Mathias Johansson was a guest speaker at the event. In his speech, he emphasized
Dirac’s approach to sound technology as distinct from conventional sound technologies:
“Different from sound effects, we are actually restoring the music as it was intended by
the artist.”

The event also featured a large-scale demonstration of a Dirac-optimized cinema
theater sound system, where the audience emphatically noticed the difference when Dirac’s
optimization was turned off.

The technology used in the OPPO Find 5 – Dirac HD Sound(R) – optimizes the acoustic
properties of the earphones shipped with the new mobile phones for the best possible
mobile music experience. Precise acoustic measurements of the earphone have allowed a
tailored digital sound processor to improve the acoustic properties of the earphone.
Technologies from Dirac are also used in high-performance HiFi, luxury cars, digital
cinemas and studios.

Dirac HD Sound removes the sound defects introduced by the earphone itself due to its
physical constraints. The result is a clear and natural sound for music playback, a
philosophy that OPPO has embraced. The technology is unique in that it corrects both the
amplitude and the timing of each tone reproduced by the earphone. Dirac HD Sound has
stirred a lot of reactions and comments on Internet forums, as it allows an earphone to
perform at altogether new levels.

Mr. Ken Kreisel, one of the founders of M&K Speaker, known for high-end studio monitor
speaker systems, listened to the sound of the OPPO mobile phone and earphone. He stated:
“While listening to the new OPPO Mobile Phone with Dirac HD Sound, the sound improvement
is tremendous and I feel almost like I am in the recording studio with my new studio
monitors. I applaud OPPO for their innovative and pioneering spirit in embracing this new
Dirac HD Sound technology.”
